Welcome to Laser Pointer Forums! If you are looking for a laser pointer or want to compare different laser pointer companies, you may want to check out the LPF Laser Pointer Company Database. The link will open in a new window for your convenience.

I heard that the Dorcy driver is capable of about 800mA for the LED, but I've also read of people have under-powering problems due to the stock driver being still in tact. Best not to quote me on either, but I've read both from past threads.

Normal white-light LEDs use around 3.7V and up to 800mA, which would be enough. Except that drivers are normally constant-current drivers. This means the native driver would try to feed a possibly much higher current to the FD, but since the FD would only accept a certain current (the one set on it), the native driver would increase the output voltage up to its maximum - no idea where that is. So, in the end it's a bit chancy. Also the added driver would mean reduced efficiency.

@meatball.... alas, i mean no driver.(i have one but the whole project is in pieces right now) i am having a heck of a time putting it all together. i have already fired 5 phrs. scopeguy can attest to that.
